Iran names 45 ships in violation of Hormuz rules (August 23, 2026) — five belong to Korea's Sinokor
The Persian Gulf and Strait Authority, a body Iran created to administer the Strait of Hormuz, published a list on August 23, 2026 naming 45 tankers it says violated transit rules. Five of them belong to Sinokor Merchant Marine of South Korea. The list also includes vessels owned by ADNOC Logistics and Services of the United Arab Emirates and its subsidiary Navig8 Tankers, and by Bahri, Saudi Arabia's state shipping line. The authority said listed vessels may face fines, detention or cargo seizure, and that ships conducting transfers with them could also be sanctioned, but did not say which rules were broken
The three lines
- Action — Iran's Persian Gulf and Strait Authority listed 45 tankers as transit rule violators
- Korea — Five vessels owned by Sinokor Merchant Marine. Seoul declined to confirm the ships
- The blank — Iran did not say what was violated. Reuters linked it to permits and transit fees
Key questions
- What is this list?
- **A roster of 45 tankers that Iran says broke its transit rules for the Strait of Hormuz.** It was issued by the **Persian Gulf and Strait Authority (PGSA)**, a body Iran created to administer the strait, and published on **August 23, 2026** local time. The vessels include very large crude carriers and LNG and LPG carriers. Ownership spans several countries — **ADNOC Logistics and Services** of the United Arab Emirates and its subsidiary **Navig8 Tankers**, Saudi Arabia's state shipping line **Bahri**, Norwegian vessels, and **five ships owned by South Korea's Sinokor Merchant Marine**. The authority said listed vessels may face **fines, detention or cargo seizure**, and added that ships conducting ship-to-ship transfers with them could face sanctions as well.
- What rule did they break?
- **Iran did not say — and that omission is the substance of the announcement.** The authority stated that the 45 vessels violated transit rules but **did not specify what any individual ship did**. Reuters reported that the measure is understood to relate to Iran's standing demand that vessels crossing the strait obtain **permission and pay transit fees**. This publication covered that fee dispute in "Hormuz transit fees: Iran 7%, Oman 3%, the US 0%," and the underlying question of control in "What a naval blockade is — why declaring one is not enough." The practical consequence is direct: **if the violation is not described, an operator cannot know what to correct.** A list that cannot be complied with functions less as an enforcement action than as an assertion of jurisdiction.
- Could the Korean ships actually be seized?
- **Iran says the option exists; there is no confirmation that anything has been done.** The authority said listed vessels may be fined, detained or have cargo seized. As of this publication, no enforcement against the Sinokor vessels had been confirmed. The South Korean government said it **could not confirm whether the listed ships are Korean**. Context matters here: conditions in these waters have shifted within days repeatedly through August. This publication reported Iran **permitting** an Iraqi tanker's transit on August 22, the 45-ship list on August 23, US sanctions on August 24, and both a tanker strike off Oman and a mine-clearance declaration on August 25. **Permission and punishment have been arriving in the same week.**
Iran published a list of 45 tankers on August 23, 2026 local time, saying they had violated its transit rules for the Strait of Hormuz.
Five of them belong to Sinokor Merchant Marine of South Korea.
The issuing body is the Persian Gulf and Strait Authority (PGSA), created by Iran to administer the strait.
1. Who is on it
| Flag / owner | Detail |
|---|---|
| South Korea | Sinokor Merchant Marine — 5 vessels |
| United Arab Emirates | ADNOC Logistics and Services; subsidiary Navig8 Tankers |
| Saudi Arabia | State shipping line Bahri |
| Norway | Vessels included |
Vessel types are mixed — very large crude carriers, LNG carriers and LPG carriers.
The composition carries a signal of its own. State-owned shipping lines of neighboring Gulf producers appear side by side. ADNOC is Emirati state-owned; Bahri is Saudi state-owned. Iran has named its neighbors' national carriers directly.
2. What Iran says it can do
| Measure | Applies to |
|---|---|
| Fines | The 45 listed vessels |
| Detention | The 45 listed vessels |
| Cargo seizure | The 45 listed vessels |
| Further sanctions | Ships conducting ship-to-ship transfers with listed vessels |
The last row is the operative one. Iran said vessels performing transfers or re-transfers with listed ships could themselves be sanctioned.
That clause extends the list's reach well beyond 45 hulls. An operator not on the list still gets caught by dealing with one that is — which is precisely the mechanism designed to make shipowners keep their distance without Iran having to enforce anything. This publication covered the same logic in "What a secondary boycott is."
3. The missing column
The defining feature of this announcement is what it omits.
Iran said the 45 vessels violated transit rules, and did not say what any individual vessel did.
Reuters reported that the measure is understood to relate to Iran's standing demand that vessels crossing the strait obtain permission and pay transit fees.
| Published | Not published |
|---|---|
| The names of 45 ships | What each one violated |
| The available penalties | The standard used to judge |
| The intent to extend liability | How to come into compliance |
An operator who cannot learn what to fix will avoid the route instead. That is the effect whether or not it is the intent — the list functions simultaneously as an enforcement roster and as an assertion of jurisdiction.
4. This waterway in August
Placing this publication's Hormuz coverage in order:
| Date | Event |
|---|---|
| August 12 | Transit fee dispute — Iran 7%, Oman 3%, US 0% |
| August 22 | Iran permits an Iraqi tanker's transit |
| August 23 | 45-vessel violation list published |
| August 24 | US sanctions across five sectors, 60 entities |
| August 25 | Tanker struck off Oman |
| August 25 | Hormuz mine-clearance declared |
Permission and punishment three days apart. This is not a situation resolving in one direction.
5. What is at stake for Korea
Sinokor is a major Korean container and tanker operator. Five of its vessels on the list means two things: Korean carriers are actively working these waters, and those vessels may fall under jurisdiction Iran claims.
Seoul said it could not confirm whether the listed vessels are Korean. No enforcement action against them had been confirmed as of this publication.
For readers outside Korea, the relevance is that Hormuz exposure is not confined to Gulf and Western operators — East Asian energy importers run their own tonnage through the strait, and Korea imports the overwhelming majority of its crude by sea. The geography is covered in "The Strait of Hormuz: 34 kilometers carrying a fifth of the world's oil."
6. What we could not confirm
- The count — outlets reported 45 or 46. This piece uses 45, carried by most.
- Vessel identities — names and current status of the five Sinokor ships.
- Enforcement — no confirmed fine, detention or seizure since August 23.
- The rules — the text and effective date of the transit regulations.
- Korean response — no government measures or company statement obtained.
- The authority — founding date and legal basis of the PGSA.
